A historic milestone in tug development was met in February when Multratug 32, the first new ‘Carrousel R RAVE Tug’ (CRT) was delivered to Novatug BV of the Netherlands.
Multraship, the operator and Novatug, are part of the Muller Maritime Group active in towing operations for over 100 years. The novel design features the RAVE tug concept jointly developed by Robert Allan Ltd and Voith Turbo GmbH & Co KG, featuring VSP drives arranged inline on the hull centreline, combined with the Carrousel Towing System on the main deck.
The Carrousel system was developed by Novatug with Multraship, while Novatug also co-operated with Machinefabriek Luyt BV to develop and manufacture the special winch that is part of the system. The unique combination of propulsion and towing arrangements provides inherently safer towing and escort operations with enhanced manoeuvrability and fl exibility in its ability to provide thrust at towline angles not practical with conventional tugs.
The CRT is designed to safely produce escort steering and braking forces approximately 50% greater than any other type of tug of similar size, and can do this at greater speeds with signifi cantly reduced risk. An additional benefi t is the ability to produce the required forces with less installed engine power, thus improving fuel economy and exhaust emissions.
